What It Is

This spindle assembly (part numbers 532187292, 192870, 187292, 532192870, 587819701) is the rotating hub that drives your mower blade, complete with a 195945 pulley. It’s designed for 42, 46, 48, and 54-inch mower decks on Husqvarna and Craftsman lawn tractors.

Fitment & Compatibility

Before buying, check these four things:

• Deck size: Fits 42", 46", 48", and 54" decks only. Measure your deck cutting width, not the tractor model.
• Model match: Works on Husqvarna YTH22V42, YTH22V46, YTH24V48, and Craftsman YT3000, YT4000, YS4500. Also compatible with many Poulan, McCulloch, and other Husqvarna-group brands using the same spindle.
• OEM vs aftermarket: This is an aftermarket replacement. OEM part numbers are listed above—verify your original spindle number matches one of these. The pulley is included and pre-installed.
• Measurements: Spindle shaft is 5/8" diameter (standard for most residential decks). Pulley is 4.5" outer diameter, 3/4" inner bore, with a 1/2" keyway. Confirm your belt width and deck mounting hole pattern (typically 3-bolt, 3" spacing).

Key Things to Know

• Quality: Solid aftermarket build with sealed ball bearings. Not OEM-grade but reliable for residential use. Some users report shorter lifespan on heavy commercial use.
• Installation difficulty: Moderate. Requires removing the blade, belt, and deck mounting bolts. You’ll need a socket set, torque wrench, and possibly a puller for stubborn spindles.
• Common gotcha: The pulley is pre-installed, but the key may be loose—check and tighten the pulley set screw after first use. Also, ensure the spindle housing gasket is intact to prevent debris entry.
• Belt alignment: If your deck has a tensioner, double-check belt routing after installation. Misalignment causes rapid wear.

Should You Buy It

Buy this if you need a direct replacement for a failed spindle on a Husqvarna or Craftsman 42–54" deck and want a budget-friendly option that includes the pulley. It’s a good value for residential mowing, but skip it if you need OEM durability for heavy commercial use or have an unusual deck bolt pattern.
